KNOW MORE :

• There are many types of energies produced when a change happens in our daily life.
• The types of energies are Atomic energy, Electrical energy, Solar energy, Radiant energy, Potential energy, Mechanical energy, Thermal energy, Nuclear energy etc.
• The two main energies are kinetic and potential energy.
• Kinetic energy - It is produced when these kind of change is happened - Electrical , Heat , Light , Sound or anything moving (Motion) etc.
• Potential energy - It is produced when these kind of change is happened - Gravitational force , Chemical etc.
• The main difference between these is kinetic energy is already done and potential energy is still doing it( Gravitational force is always there ).
